Fig. 2 shows the streams according to an embodiment of the present invention for the method in source physical machine to purpose physical machine hair data
Cheng Tu, Fig. 4 show the structure of the device 40 according to an embodiment of the present invention for source physical machine to purpose physical machine hair data
Figure, the device 40 is for executing method flow shown in Fig. 2, and device 40 includes encapsulation unit 41, judging unit 42, determines list
Member 43, cache unit 44 and transmission unit 45.
With reference to the accompanying drawing, the embodiment of the present invention is specifically described.
Fig. 6 shows the structure chart of the communication system according to an embodiment of the present invention comprising device 40 shown in Fig. 4.Example
Such as, which is mounted in source physical machine 61, and source physical machine 61 has multiple CPU (central processing unit) (figure does not regard).
As shown in Fig. 2, encapsulation unit 41 will be by the processed number of correspondence CPU in multiple CPU in encapsulation step S21
According to progress generic route encapsulation (Generic Routing Encapsulation, GRE), and form the tunnel of transmission data
(tunnel)。
In this example, corresponding CPU is, for example, CPU1, and 41 pairs of encapsulation unit carry out GRE encapsulation by the processed data of CPU1,
Tunnel A between formation source physical machine 61 and purpose physical machine 62.
In judgment step S22, whether judging unit 42, which judges to cache in CPU1, is used for tunnel A in active physical machine 61
Network interface, if so, then enter sending step S25, otherwise enter determine step S23.
Have multiple network interfaces, such as network interface shown in fig. 6 611 and network interface 612 in source physical machine 61, by network interface 611 or
Network interface 612, source physical machine 61 send or receive data.It should be appreciated that although Fig. 6 shows two network interfaces 611 and network interface 612,
But the quantity of network interface can be any, and it is unrestricted.
For example, the network interface 611 or 612 for tunnel A is not cached in CPU1, then determining step S23, really
Order member 43 is determined according to the source network protocol address of tunnel A, the purpose internet protocol address of tunnel A and the mark of CPU1
Network interface.
Fig. 3 shows the specific flow chart of determining step S23, and Fig. 5 shows the structure chart of determination unit 43, such as Fig. 4 institute
Show, determination unit 43 includes searching unit 431 and computing unit 432.
As shown in Figure 3 and Figure 5, in finding step S231, searching unit 431 utilizes equivalent route (ECMP), finds this
Source physical machine 1 has multiple network interfaces, such as the network interface 611 and 612 in this example.
Then, step S232 is being calculated, computing unit 432 is to the source network protocol address of tunnel A, the purpose net of tunnel A
The mark of network protocol address and CPU1 carry out Hash calculation, to determine a network interface in network interface 611 and 612.
Wherein, the source network protocol address of tunnel A is the internet protocol address IP1 of source physical machine 61, the purpose net of tunnel A
Network protocol address is the internet protocol address IP2 of purpose physical machine 62.The mark of CPU1 is for example exactly the label " 1 " of CPU1.
In this example, computing unit 432 carries out Hash calculation to the label " 1 " of IP1, IP2 and CPU1, so that it is determined that
Network interface 612.
Since the CPU of data per treatment is not fully identical, for tunnel A, although IP1, IP2 be it is fixed,
But the label of CPU is not identical, thus to IP1, after the label of IP2 and CPU have carried out Hash calculation, determining network interface
Also not identical, therefore the data transmitted every time are not all transmitted by the same network interface, in this way, data transmission may be implemented
Load balancing.
Fig. 2 is returned to, in caching step S24, network interface 612 is cached in CPU1 by cache unit 44, and enters sending step
S25。
In sending step S25, the data after above-mentioned encapsulation are sent to purpose physical machine via network interface 612 by transmission unit 45
62。
In addition, being flowed if judging to be cached with the network interface 612 for tunnel A in CPU1 in judgment step S22
Journey is directly entered sending step S25, and the data after above-mentioned encapsulation are sent to purpose object via network interface 612 by transmission unit 45
Reason machine 62.
Wherein, different tunnels can be formed between source physical machine 61 and different purpose physical machines, in this example, source object
Tunnel A is formd between reason machine 61 and purpose physical machine 62.In addition, source physical machine 61 and another object physical machine (scheme not regard) it
Between can form tunnel B (figure do not regard).
In each CPU, the different network interfaces for different tunnels can be cached.For example, having been cached in CPU1 for tunnel
The network interface 612 of road A, for the network interface 611 of tunnel B and the network interface in other tunnels.Equally, use can be cached in other CPU
In the respective network interface of tunnel A, tunnel B and other tunnels.
As can be seen that after having cached the network interface 612 for tunnel A in CPU1, when source physical machine 61 will be transmitted again
When data are to purpose physical machine 61, that is, be using tunnel A come when transmitting data, it, can if the data are handled by CPU1 again
Directly to send data using the network interface 612 for tunnel A cached in CPU1, go to select without repeating Hash calculation
Network interface is selected, therefore the performance of data transmission can be improved.
As above, by the invention it is possible to realize the load balancing of data transmission, while the property of data transmission can be improved
Energy.
The present invention also provides a kind of computer-readable storage medium, storage medium has the instruction being stored therein, when
Instruction is performed, so that computer executes source physical machine to the method for purpose physical machine hair data, instruction includes:
Encapsulation instruction will carry out general road by the processed data of correspondence central processing unit in multiple central processing units
By encapsulating, to form the tunnel of transmission data；
Decision instruction judges the network interface for tunnel in active physical machine whether is cached in corresponding central processing unit；
Determine instruction, when judge in corresponding central processing unit it is uncached have network interface when, according to the source network agreement in tunnel
The mark of address, the purpose internet protocol address in tunnel and corresponding central processing unit, determines network interface；
The calculated network interface of computing unit is cached in corresponding central processing unit by cache instruction；
Transmission unit will be sealed when judging to be cached with network interface in corresponding central processing unit or after having cached network interface
Data after dress are sent to purpose physical machine via network interface.
